The two words, Adam Smith, contain a strange power. Many years ago, I found myself in an African country having what the official communiqués joyfully describe as "a frank discussion" (a monumental row) with a very bright young official from the World Bank who had recently acquired religion. The religious belief in question was a complete (and, in this case, utterly naive) adherence to laissez-faire economics. At a certain point in the conversation, the official produced with a huge flourish the supposedly knock-down argument that the recommendation of the World Bank was just what Adam Smith would have recommended.
